ATTACHMENT FOR WINDOW-BLINDS.

SPECIFICATION forming part of Letters Patent No. 306,994, dated October21, 1884.

(No model.)

To all whom, it may concern Be it known that I, ANDREW J. AVERY, ofLynn, in the county of Essex and Commonwealth of Massachusetts, haveinvented a new and-Improved Attach ment for Blinds, of which thefollowing, taken in connection with the accompanying drawings, isa'specification.

This invention relates to blinds, doors, and similar objects, and hasfor its object to provide a device whereby ablind or door adapted toswing outward horizontally on its hinges may be positioned and held atvarious points, opened or closed, or at pointsintermediate between thesetwo extremes.

In the accompanying drawings, Figure 1 is a perspective view of myinvention, and illus trates the form and construction thereof. Fig. 2 isa perspective view of awindow-bliud having the device shown in Fig. 1attached there to, and illustrates the manner of using my invention.

The ribbon A is composed of metal or other suitable material, and ismolded or east or otherwise formed with a contour substantially asrepresented in said Fig. 1, and is provided with notches a, formed inthe one side or edge thereof, and with screw-holes b, as shown. Thisribbon is attached to the blind in close proximity to the blind-hinge,as represented in Fig. 2. Connection with the blind is effected byscrews or rivets made to pass through the ribbon into the blind in suchmanner as to form a pivot on which the ribbon may be oscilia-ted. Theposition of the ribbon relatively to the hinge B of the blind is such asto permit of being depressed sufficiently to engage the shank of thehinge B in the notches of the ribbon, as shown in Fig. 2.

In Fig. 2 the blind is represented as part way open, the shank Bbeingina notch formed in the ribbon. The blind is prevented from swinging ineither direction, for if it is desired to change the position of theblind the person has only to place one hand upon the ribbon and elevateit to the position indicated by dotted lines X X. The blind may then beswung in either direction to further open or close the same, the ribbonmeanwhile being elevated above the shank B. When the desired position ofthe blind is obtained, the ribbon A is again depressed to engage theshank B in the notch formed in the ribbon. It will be evident that theremay be as many fixed positions of the blind as there are notches a inthe ribbon, and these notches may be more or less frequent, as occasionand taste demand. L I have represented my invention as combined with ablind having hinges, the same as are now in common use, though I am byno means limited to the particular construction of hinge shown.

hat I claim, and by Letters Patent desire to secure, is

1. Asa new article of manufacture, the metallic ribbon bent asdescribed, and provided with notches at its lower edge to engage thehinge and pivotal apertures, whereby it may be pivoted to the blind,substantially as and for the purposes specified.

2. In combination with the lower hinge, constructed as described, thebent ribbon having notches to engage said hinge, and apertures by whichit is pivoted by means of suitable screws to the blind, the wholeadapted to operate substantially as specified.

Signed at Lynn, Massachusetts, in presence of two witnesses.
